CABINET-DOOR.

Specification of Letters Patent.

Application filed November 80, 1909.. Serial No. 530,558.

To all whom it may concern:

Be it known that I, Hueo R; Knnns'rnn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Cabinet-Doors, of whichthe following is a specification.

.This invention relates to that type of cabinet door which is adapted toform a closure for the cabinet when swung into one position, and which,when released from such position, will swing into a position parallelwith the side walls of the cabinet body, and when the latter position isreached will be acted upon by suitable mechanism and drawn back into theinterior of the cabinet body.

The object of the present invention is to construct a door with theabove described properties, in which the operation will be automaticwhich draws it back into position.

' within the interior of the cabinet; in which the movement will beautomatic which swings it into position to be acted upon by themechanism to draw it back into the interior of the cabinet; which willbe securely locked when it is in the position to form a closure for thecabinet; in which the door will be held against swinging movement whileit is being drawn into or out of the cabinet body; in which the doorcannot be swung into position to form a closure for the cabinet bodyuntil it has been fully withdrawn from the interior of the cabinet bodin which the upper and lower edges which is capable of being attached tothe ordinary cabinet body without any change in the appearance orconstruction thereof.

The invention consists in the features of.

construction and combination of parts here.- lnafter described andclaimed.

In the drawings, Figure 1 is a vertical sec-- 7 body; Fig. 5, a planview of the parts shown swung into position to form a closure for thecabinet; Fig. 7, a section on line 7-7 of Fig. 6, showing the actuatingmechanism in elevation; Fig. 8, a modified construction of the rack andpinion shown in Fig. 3; and Fig. 9, a cross section through the plateshown in Fig. 8.

The cabinet body consists of side walls 9, a rear wall 10, a top wall11,- and a bottom wall 12, all constructed in the manner ordinarilyemployed in manufacturing cabinet bodies. Positionedadjacent to the top.wall 11 and the bottom wall 12, and secured to one of the side walls 9,are plates 13 and 14,

preferably of angle-iron formation. Each' Patented June 21, 1910.

16, and this toothed edge constitutes, in

effect, a rack; and meshing with the teeth of these racks are pinions 17and 18 which are mounted on a rod 19, which has its ends journaledwithin plates 20 and 21. These plates are also preferably of angle-ironformation and are secured to a section 22 of a cabinet door 23, whichsection is capable of a movement parallel only with the side walls ofthe cabinet body and may be termed the sliding section. The lates13 and14., as

shown, are of angle-iron or'mation and have one of their extendingportions formed as above described to constitute racks, the otherprojecting portion 24 forming a trackway upon which travel companionrollers 25 and 26 carried by the plates 20and 21.

Attachedto the section 22 of the cabinet door is a cable 27, whichpasses over, an idler 28 jou'rnaled in the side wall 9 andpositioneduadjaoent to the rear wall 10 ofwhich cable has a weight.

the cabinet body, 29 secured to its end.

The cabinet door is composed ofthe section 22, which has been termed thesliding section, and a section 30, which is capable of movement parallelwith the sides of the cabinet body, and is also capable of a swingingmovement which will bring it into position to form a closure for thecabinet body, and this section may be termed the swinging sectioazn Thetwo sections are hinged toand well known type of construction. Lo

3 cated near the path of travel ofthe section stop member would act tois a stop member 32 which is secured to the cabinet body and whichprevents the door for swinging while it is being moved in or outtherefrom. By referring to Fig. 5, where this stop member is shown morein detail, it will be seen that with the parts as shown in this figure,the section 30 of the cabinet door is in position to be swung at rightangles to the section 22 and form a closure for the cabinet; but if theparts were in a positiom so that the hinges 31 would lie on the o positeside of the stop member 32, it won (1 then be seen that the revent anyswinging movement of the section 30; thus no swinging movement of thesection 30 is possible until the section has been fully drawn out fromthe interior of the cabinet, and no movement tending to draw the doorinto the interior of the cabinet is. possible until the section 30 hasswung into the posit-ion parallel with the sides of the cabinet body,because not before it has reached such posltion will it be able to passby the stop member. When the section 30 is swung into position to form aclosure for the cabinet body, it is desirable that some locking means beem loyed for retaining the section in such position. Thelocking'meansshown in Figs. 6 and 7, for accomplishing this pur ose,consists of an actuating member 33 hel normall outward under springtension, and attache" to the actuating member isa bell crank lever 34connected to the locking member 35. -By referring to Fig. 7, it will beseen that a push inward upon theactuatmg member 33 will cause the bellcrank lever 3 1 to assume a position which will retract .the lockingmember 35' from engagement with a recess 36 formed in the section 30,allowing, said section to swing into position to bedrawn into theinterior of the cabinet body. As shown in Fig. 5, one edge of thecabinet body is cut away at 37, forming an overhanging led e 38, whichacts as a sto against which t e .door rests when it. 1s swung intoposition to form a closure for the cabinet.

In Fig. 8 is shown a modified construction, which consists of a rackformed with a plurality of holes 39 in place of the gear teeth 16; andin place of thepinions 17 and 18 is shown a toothed wheel 40, theformation of the-teeth 41 being such as to adapt them to enter the holes39 in thestra'ckway.

The operation is as follows: Whenthe operator releases'the mechanismshown in Fig. 7, the spring hinges 31 will act to swing the section 30into the position showndn Fi s. 1 and 2. When'the section has reachedsuc positionkitwill then be clear of the stop member, and the tensionproduced by the weight 29 will cause the sliding and swingin" sectionsto be pulled into the interior o the cabinet body, the sections being Aguided in their rhovements in and out of the cabinet body by the pinions17 and 18 and by the rollers 25 and 26. All of these movements necessaryto the positioning of the door within thecabinet body are accomplishedautomatically, the only action on the part ofthe operator being themoving of the actuating member 33 to release the locking mechanism. Thestop member 32 forms means whereby the door cannot be drawn into theinterior of the cabinet until it has which course of travel would causea bind-' ing between the door and the trackway u on which it slides,thus making the door difficult of operation.
